I have created a new table in Sage CRM named Sites. I made it a primary entity and there will be multiple rows recorded in Sites for any particular company.
I would like to complete setting us Sites.
I would also like to add a tab in Company for Sites to show a list of all sites associated with any particular Company. I go to Customization --> Company --> Tabs --> Company, and I try to add a new tab named Sites. The Action is <other>, the system action however is not showing <siteslist>. How do I create a custom system action?
I would appreciate your feedback and assistance.

When creating the sites tab select an action of custom file. You will be asked to enter the file to use. This needs to be a .asp file that you have written in the custom pages directory.
